Update main.go

Make license detection configurable via LicenceTerms.json  

- Updated `hasLicense` function to dynamically load license terms from `../LicenceTerms.json`.  
- Falls back to default terms if the file is missing or has invalid JSON.  
- Ensures no additional functions are introduced for simplicity and maintainability.
